coreos-meta-translator: add gcp cloud launchable to release.json

[zonggen]

As AMIs have their own field images under the aws key, I think it might make sense for GCP to follow the same rule, adding an image field under the gcp key and rename the original image key to name.

If this is reasonable, it should be followed by updating fedora-coreos-stream-generator to support this PR. Finally, download page could read the GCP cloud launchable metadata from e.g. stable.json instead of meta.json

Example JSON field in release.json:

"gcp":{
   "artifacts":{
      "tar.gz":{
         "disk":{
            "location":"https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200517.3.0/x86_64/fedora-coreos-31.20200517.3.0-gcp.x86_64.tar.gz",
            "signature":"https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200517.3.0/x86_64/fedora-coreos-31.20200517.3.0-gcp.x86_64.tar.gz.sig",

Closing as we inline to not exposing the GS URL, thanks for the link 👍

hey @zonggen - I think the only thing we agreed on so far is to not expose the URL - so I think we'd still want the project/family/name.

So, IIUC, something like:

"gcp":{
   "artifacts":{
      "tar.gz":{
         "disk":{
            "location":"https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200517.3.0/x86_64/fedora-coreos-31.20200517.3.0-gcp.x86_64.tar.gz",
            "signature":"https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200517.3.0/x86_64/fedora-coreos-31.20200517.3.0-gcp.x86_64.tar.gz.sig",
            "sha256":"e7a766cbba51fc35cb55d471c42ecc824519c6a3bd8a95577749676aeebf9b9c"
         }
      }
   },
   "image":{
      "project":"fedora-coreos-cloud",
      "family":"fedora-coreos-stable",
      "name":"fedora-coreos-31-20200517-3-0-gcp-x86-64"
   }
}
